G40UH - LEDs Alternating Slow Flash

- Combustion air inducer engergizes with a heating demand.
- Burners light but fail to stay lit
- After 5 tries LEDs flash alternating slow flash

Completed:
- Installed new control board
- Check that sensor is properly located and wires properly attached
- Check for broken sensor
- Tested continuity across sense wire
- Tested resistance btw sensor rod and unit ground
- Checked resistance/ground to the burner box.

How do I check the mircroamp from the flame? Where do i connect multimeter wires? What is normal microamps?

Any other suggestions? Should I just replace the flame sensor?
